Storage Management Strategies for the CIO
Access "Host-based replication"
This article is part of the Vol. 5 No. 10 December 2006 issue of The hottest storage technology for 2007
While the lines of distinction among data protection technologies such as backup, continuous data protection and replication have blurred, host-based replication can play a key role in your overall data protection strategy. The lines between data replication and data protection software products are becoming blurred as storage managers wrestle with the familiar trinity of data protection: centralized backup, disaster recovery (DR) and business continuity. With some industry observers predicting a convergence of backup, continuous data protection (CDP) and data replication software in the next few years, choosing a host-level (server-based) data replication product has become much more complicated. The similarities that host-level replication software products have with backup and CDP products contribute to the difficulty in understanding where one ends and the other begins. For instance, CA XOsoft's WANSync replication software suite includes options that could allow it to fit into all three of these categories. Its WANSync high-availability option (... Access >>>
